Ubuntu 12.04 ESM: USN-3798-2 Moderate: Linux Kernel Denial Of Service

ubuntu
Calendar Grey October 23, 2018
Dist Ubuntu Esm H88
Vulnerabilities within the Linux kernel have been addressed in the update for Ubuntu's Trusty HWE, boosting overall system reliability.
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-lts-trusty: Linux hardware enablement kernel from Trusty for Precise ESM

Details:

USN-3798-1 fixed vulnerabilities in the Linux kernel for Ubuntu 14.04

LTS. This update provides the corresponding updates for the Linux

Hardware Enablement (HWE) kernel from Ubuntu 14.04 LTS for Ubuntu

12.04 LTS.

Dmitry Vyukov discovered that the key management subsystem in the Linux

kernel did not properly restrict adding a key that already exists but is

negatively instantiated. A local attacker could use this to cause a denial

of service (system crash) or possibly execute arbitrary code.

(CVE-2015-8539)

It was discovered that a use-after-free vulnerability existed in the device

driver for XCeive xc2028/xc3028 tuners in the Linux kernel. A local

attacker could use this to cause a denial of service (system crash) or

possibly execute arbitrary code. (CVE-2016-7913)

Update Instructions

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.04 ESM:
  linux-image-3.13.0-161-generic  3.13.0-161.211~precise1
  linux-image-3.13.0-161-generic-lpae  3.13.0-161.211~precise1
  linux-image-generic-lpae-lts-trusty  3.13.0.161.151
  linux-image-generic-lts-trusty  3.13.0.161.151

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
